Iran’s Islamic Revolutionary Guard Corps (IRGC) says it has temporarily closed the Strait of Hormuz “until further notice” following an incident involving a commercial vessel in the waterway, according to Iranian state media reports. Multiple outlets report that the IRGC navy says it fired warning shots at a ship it claimed attempted to transit along an “unapproved” or “illegal” route. In the IRGC account, the crew did not correct its course after being warned, and one vessel was hit after warning fire, with the IRGC asserting it was attempting to safeguard maritime security. State media statements reported by outlets say no vessels will be allowed to pass through the strait until the IRGC says US “interference” ends. DW also reports that the IRGC links any reopening of the strait to the end of US involvement in the region. Several reports describe the IRGC’s position that additional violations or attacks would be met with a forceful response. The sources provided do not include independent verification of the damage claims or the vessel’s routing details, nor do they provide additional information on the vessel’s nationality or status after the incident.
